Application filed 1 311119. 1907. Serial no. 369.157.

To all whom it may concern? Be it knownthat I, ANTON Born, a citizen articular ob ect of --the invention is: to urnis'h a certain novel construction of agitator or beater for thoroughly mixing and stirring the ingredients, as will-be hereinafter particularly ppintedioutand claimed.

Intlie drawings Figure '--1 is a side eleva- Fig. '2 is-a perspective view of the agitator,- Fig. 31s a planof same.

, The'operating'mechani'sm is mounted 0n the substantial standard 1, rovided with endof this driving 'sha t 3,0utside the journal bearing carries't'he beveled gear5, which meshes with the beveled" gears 6 and r7 mounted loosely on the vertical shaft 8, .journaled in a suitablev extension of the standard and held in position by the collars 9 and 10. Between the-gears 6 and 7 is the clutch collar 11 secured to the shaft by spline and roove, and this collar is shifted bythe ham? lever 12 to engage either of the gears 6 and 7 to rotate'the shaft 8 in either direction.

in the wellknown way. The lower'end of the shaft 8 is provided with the agitator for thorou 'hl'y beating up the dough mixture. I

ecured on the shaft a convenient distance apart for the depth of the dou h receptacle at right angles to the axis of t e shaft, and in planes at right angles to each other are the bars or rods 13 and 14, and secured to the ars and extending" from the upper to the lower bar are the pairsof blades 15, 16 and -17, 18. These blades are befntqspirally and the two pairs of blades are arranged in alternate positions, so that one pair will contact "with the dough mixture between the. spaces left bytheother pair. The blade 15, for

goods, and the like, and the example, extends spirall from vthe end of one 'bar 13 to the end 6 the otherv bar 14. The'other blade'1'6 of the pair extends from a point about midway between the bar 15 and the shaft 8, to a corresponding point 'on the bar 14, whilethe other pair of blades 17' and 18 occupy positionsintermediate of the blades 15 and 16 on the op osite'portions of the bars 13 and14; The ower ends of the blades 15,16, 17 and 18 extend a shorttdistance below the bar 14, and at thebase are broadened out, as shown at 20,-so atthe bottom the blades'will sweep over and scrape the entire bottom surface of the receptacle.

2'11is the dough receptacle .of cylindrical shape, and mounted an secured in fixed 'positiorLin any well known way on the ad'ust able shelf 22, which shelf is carried by thecollar 23 mounted on the shaft 24 secured.in

lugs 25 on the main standard 1 When the ingredients are placed in at receptacle 2]., the table 22-;is raised-tobring the agitator within the 'receptacle,and the table is then looked in screw 26. The agitator s aft is then'rotated as above described, usually in-a direction to cause the spirality of the blades to. carry osition bythe ,set

the material, while agitating and-beating 1t to the bottomv of ther'eceptacle. often be of advantage, however, to beatu'p the mixture by raising it from the bottom, and in that event, the shaft is rotated in the It may oppositedirection, thus raising the ingredients and allowing them to drop back around the agitator;

Having thus described my invention, what I claim as new, anddesire to secure by Letters'Patent, is;', 1

In a dough, ing machine, the combinafor, with means or rotatin same, said agitatorcomprising four spira blades. arrangedon opposite-portions of the agitator. shaft, each of said blades of the several pairs being secured at different distances from the axis of the shaft, one pairoperating on the spaces 100 left by the other pair, the lower ends 0 said blades being extended downwards and, broadened out to completely scrape the bottom of the receptacle.
